Since entering the 21st century, the development of fast fashion has faced a number of environmental problems. The design of circular economy is the best way to deal with fast fashion pollution, while the existing recycling system, traditional waste disposal methods are inefficiencies and are no longer enough to deal with the pollution caused by today's fast fashion industry. So this paper discusses some cutting-edge technologies to meet the development of circular fashion and achieve the approaches for sustainable development of fashion industry. After a specific analysis of the pollution of the fast fashion industry to the climate, water and the waste caused, this paper introduces the infrared technology to accelerate the sorting of clothing raw materials in the waste, enzymatic technology to process and degrade the raw materials, and the use of new sustainable materials in three steps to obtain an advanced technology support, sustainable fashion circulation system. In the future, this improved fast fashion circulation system still needs more experiments to be tested, also the government and relevant departments need to formulate relevant policies to support the development of this system. On the other side, the fast fashion industry's pollution of the environment, especially water bodies, and its treatment methods need to be studied.
